webphone dev with SL apps in Visual Studio 2010

Hello. There are quite a few threads, comments dealing with Silverlight apps, but many of them lack information about webphone devices and background support related to SL. I found the How to implement web to web video calls using Silverlight camera access? sample program on the Ozeki VoIp SIP SDK webpage and think itÃ¢â¬â¢s instructive enough to start a business application with webphone. After testing the sdk in Visual Studio 2010 I went on using it. It sounds a bit like sticking to this sdk, but I have experienced that the support team is really good: they have helped me significantly in my work.
